Mass spectral molecular weight (M.W. 390.54) of KP-3, an antifungal substance isolated from Bacillus sp. B-003, and its sturctural analysis from ^(13)C/¹H-NMR and hetero-COSY indicated the empirical formula to be C_(24)H_(38)O₄ and the chemical name to be Bis(2-ethylhexyl)phthalate, an important plasticiser. The oily compound was soluble in ethanol, methanol and ethyl acetate, but was not soluble in distilled water and hexane. This substance was stable to heat, having -46℃ and 231℃ as melting point and boiling point, respectively. The KP-3 was visualized in anisaldehyde-sulfuric acid (violet), phosphoric acid (UV) and molybdophosphoric acid (blue) while not in Ninhydrin test.

A bacterium producing an antifungal compound KP-3 isolated from soil was selected and identified as Bacillus sp. B-003. The antibiotic substance KP-3 was active against Microsporum gypseum, Trichophyton rubrum and Epidermophyton floccosum at the concentrations of 0.15 - 10.0 ㎍/ml except Candida albicans. This compound was isolated from the fermentation broth (12L) and completely effected by chromatography on silica gel. The Rf value of purified KP-3 (5mg) was 0.91 when TLC plate was developed with methanol - ethyl acetate (1.5, v/v).

Particulate matter (PM) is one of the major indoor air pollutants especially in the subway station in Korea. In order to remove PM in the subway station, several kinds of PM removal system such as roll-filter, auto-washable air filter, demister, and electrostatic precipitator are used in the air handling unit (AHU) of subway station. However, those systems are faced to operation and maintenance problems since the filter-regeneration unit consisting of electrical or water jet parts is malfunctioned due to the high load of particulates and the filter material needs periodic replacement. In this study, we presented the novel air filtration system utilizing cyclone panels for removing PM in AHU. The system was designed based on numerical simulation test in terms of particle collection efficiency and pressure drop. The mock-up model was manufactured for experimental test and the results showed good feasibility.

Many passengers complain about the air quality of subway stations, mostly due to the dust. Usually, this dust is usually originated from tunnels, passengers, or outdoor air. As for now, the dust from tunnels and passengers is not easy to control, but relatively easy to control that from outdoor air. In this study, the effect of outdoor air on the subway air quality was investigated, and various factors was found to be effective. Based on these results, some strategies for the improvement of air quality in subway stations were suggested in this study.

The management of particulate matters (PM) concentration is very important in managing indoor air quality of subway stations. In this study, the effect of track type and nearby road traffic was investigated. PM concentration of subway stations with concrete only track was lower than that of stations with some ballast track. Among the subway stations with ballast track, PM concentration was higher at the stations with smaller portion of ballast track. PM concentration of outdoor air was proportional to the amount of road traffic. However, any direct relationships between traffic and PM concentration of subway stations was not observed.
